Remarks

User Common consists of workstation information that resides in memory. Programs access User Common to obtain current workstation configuration and state data. Each User Common word stores a separate piece of information, such as cursor line and element position, current image and graphics frame, current logon initials and project number.

User Common values can be placed directly into local command entries by using #UC(word) to replace a parameter or keyword value. For example, LB 1 #UC(13) sets the image loop bounds from 1 to the value stored in User Common word 13.

Caution !

Do not alter User Common. If you incorrectly modify a UC value,
you may need to exit and restart McIDAS to reinitialize its state.
